To aZZ whom z'thmay concern: Be it known that l, CHARLES ALBERT TA- JUM,a citizen vof the United States, residing at New York, in the county ofNewl YorkA and State of New York, have invented a new and: usefulADevice for Measuring Glass, of whiclithe following is a full, clear, andeXact description, to the accompanying drawings, forming part of thisspecification', in which:-.

Figure l is a longitudinal section a portion of a glass' furnace havingone in glass measuringfdevices,

lwhich bottles and various foi-m of my improved measuring device appliedthereto.

Fig. 2 is of Fig.' 1.

This invention relates to an improvement and is designed to provideas'impleuand efficient device for measuring successive'predeterminedquantities of molten v'glass for delivery to molds in other articlesarepressed into shape, or pressed and blown.

f anextension or vforeliearth of a-glass furglass, and froinwhich the of'glass for y invention providesa device of this character which canreadily beconnected to receptacle containing molten proper quantitieseac mold can be readily and quickly measured and delivered to the molds.e precise nature of my invention will be 'reference ,to the accomwhichwill now be deiia'ce, or other 4rious'chaiiges can be made in thedetails of v the parts, without departing from the spirit ,extensionaiid'scop'e of my invention as defined inthe vappended claims. 4o

Referring to the construction shown in ythe drawings, ythe numeral 2designates a glass furnace 4having a forehearth or eXtenvsion 8. heoverhanging bottom 4 of this eed-'out'.openingsr 5. -6 isv a member.which is xedly connected to the bottom 4 or to the furnace in 'any'.desired manner .and Awhich is provided withtwo feed openings 7 there-'openings- 5.l

single de- 'bers 6 and 8 are each providedwith suitable guidingsurfaces, such as s liwii 'at lil-and reference being had through .i

lwith a Sectional View Qn the line H ii uring member isv then shifted togeneral arrangement of v other measurin 'member 13 is th o r forehearthhas two separated 12. Mounted for reciprocating sliding` movementbetween the two members 6 and 8, is

' havingitsupper and tions which coperate with the guiding surfaces llon the members 6 and 8, respectively. The member 13 is providedwith' twomeasuring openings 14 and 15, each'of, which can be brought to registerwith one-of. the openings in the members 6 and 8.r

The three members- 6, 8 and 13 are preferably of hollow form, and eachis provided inlet pipe 16 and outlet pipe 17for the circulation of acooling medium Such as airor water, so as to prevent the parts frombecoming overheated. The members may be formed of any suitablerefractory material.

18 designates a mold carrier for the molds oi' other containers 19. Eachof the openings 5 is provided with a controlling stopper 23 which issecured to a rod 22 actuated by a lever 21.

The operation is as follows: The movable i measuring member 13 is' movedto a position in which oneof its measuring openings or cavitiesregisters with one of the openings 7 in the feed member 6, so as topermit glass to flow into the measuring opening, which, at this time, isout of register with-the opening in the delivery member 8.- Themeasbring the lled measuring opening into alinemen't with the opening inthe delivery-member and 'thus feed its contents through said openinginto This movement of the member 13 brings the other measuring in intoregister -with the other feed opening inthe member 6, so that wliile oneof the measuringopenings is being discharged, the g opening is beingiiiled. The en moved in the opposite direction to bring the lastlille'd'nieasuring opening into register with the delivery opening andthe emptied measuring opening into register with the other feed openingin the member 6. his movement'of the member 13'. is repeated e.movements of said member cause it to act as a shear to shear'the columnof glass.

My invention provides a measuring Afeed device which is extremely simplein` its construction and mode of operation, land b y or other receptacleinto molds or forming devices. I do not desire to limit myself to theparticular embodiopening therethroughout 'the operation.

member being intermediate tom 4c, said member may fpart of said bottomor of the furnace. rious other changes may y'tails of construction andarrangement o 'feedmember having two openi having two openings ments ofmy invention which have herein shown and described, as it is obviousthat various changes may be made therein. T hus, instead of forming themember 6 as a separate member secured to the forehearth botbe formedas'a :Tebe made in the dethe parts,

The combination of a furnace for melting glass havinga plurality of openings through va portion of the bottom thereof, of amolten glass measuring and delivering device connected thereto, saidmeasuring an delivering device comprising a` said measuring anddelivering a stationary feed member therethrough communicating withopenings through the bottom ofthe furnace,-a stationary delivery memberhaving an opening therethrough internected thereto, device comprising'mediate the openings through the feed mem- `bei', and a reciprocatingmeasuring Amember a plurality of measuring cavities the distance betweenthe measuring half the distance having therein, cavities being equal toone between the cavities in the feed member, said measuring member beingmovably mounte the feeding and discharging members, whereby one of itsmeasuring cavities is in register with one of the openings stationary-opening will be brought into register scribed.

thereof, cfa molten `glass measuring and deivering device conmemberbeing movably bers;

3. Means for measuring an 'delivering moltenglass, comprising astationary feeding member having a plurality of feed openingstherethrough communicating with a source of supply of molten glass, amovable measuring member directly below the lso feedi I ing member andhaving a plurality of meas-v uring cavities therethrough, and a fixeddelivery member immediately below the measuring member and having asingle discharge opening',

the openings in said members being y arranged whereby as'the measuringmember is shifted one of its measuring openings will- 'Y be brought intoregisterwitli one of the feeding openings and another measuring with thedelivery opening, substantially as de- 1 4:.

a molten glass `measuring and delivering de-v vice connected thereto,said measuring an delivering device comprising a stationary feed memberhaving two openings therethrough communicating with openings through thebottom of the furnace, a stationary delivery' member,

measuring member having a plurality of measuring cavities therein,

mounted intermediate the feeding and discharge members, whereby itsmeasuring cavities may be al'- ternately brought into receiving anddelivering relation to the openings in the feeding and dischargemembers, and
